Detailed Description

Dorman 923-002 is built for vehicles that use a rear lamp circuit board to manage tail light operation. It serves as an OE-style replacement for select 1988-2000 Chevrolet and GMC trucks, Suburban models, Tahoe, Yukon, Blazer, and 1999-2000 Cadillac Escalade right-side applications. If the original board has heat damage, corrosion, or an open circuit, this replacement restores the electrical path needed for proper tail light function.
